UNITED STATES RODER NYBERG. OF PICHER. OKLAHOMA.

CYLINDER HEAD.

Application filed January 19, 1922.

T all whom it may concern.

Be it known that I, RODER W. NYBERG, a citizen of the United States. residing at Picher, in the county of Ottawa and State of Oklahoma. have invented certain new and useful Improvements in a Cylinder Head; and I do hereby declare the following to be a full. clear. and exact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a head for internal combustion engine cylinders.

It is particularly aimed to provide a construction which is practically indestructible so as to overcome the objections to and to supplant the use of the usual cylinder heads which are constructed of cast iron.

Another object is to provide a construction made of steel and embodying inner and outer sections connected by bolt-receiving tubing and with the tubing electrically or otherwise welded to the sections.

Further objects are to provide a head which will have a larger circulating space for the cooling water of the internal co1nbustion engine and one in which the water circulating space may be more readily cleaned.

Additional objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating one practical embodiment thereof:

In said drawings Figure 1 is a plan view of the improved cylinder head in inverted position;

Figure 2 is a side elevation of the cylinder head in inverted position;

Figure 3 is a cross sectional view on the line 3-3 of Figure 1;

Figure 4 is a cross sectional view on the line 44 of Figure 1;

Figure 5 is a plan view of a modified form of cylinder head and Figure 6 is a cross sectional view on the line 66 of Figure 5.

Referring specifically to the drawings, the cylinder head comprises inner and outer sections A and B of substantially bell shape and to this end respectively having annular walls 7 and 8 and cover walls 9 and 10 respectively. These sections A and B are preferably made of forged rolled steel.

Intermediate the walls 7 and 8 an annular row of tubes 11 is disposed and which tubes Serial No. 530,423.

are open at each end and project into the wall 10. The tubes 11 are also preferably of forged rolled steel and relatively heavy. At 12 the tubes 11 are welded electrically or otherwise to the walls 7 and 8. Also, at 13, the ends of said tubes are electrically or otherwise welded to the wall 10. As a result of the use of steel and the welding of the parts together as described, practically an unbreakable head is provided. I

Attention is called to the fact that the space between the walls 7 and 8 is of a width substantially the same as the diameter of the tubes 11 and thus in assembling the head with the lower edge of both sections in the same plane the positioning of the tubes 11 between the walls 7 and 8 will automatically properly concentrically position the section A relatively to the section B especially as the upper ends of the tubes extend into the wall 10.

Openings 14 through the tubes 11 accommodate the usual fastening bolts which secure the cylinder heads to cylinder castings or blocks.

Attention is called to the fact that the construction provides a relatively large circulating space at 15 for the cooling water of the engine. The connection in the water circulating system of the engine may be made at nipples 16 suitably disposed in the wall 8.

A base may be provided at 17, of any usual or desirable construction, to facilitate attachment of an air starter. This base is welded in place and has an inwardly extending nozzle. at 18 bridging the walls 7 and 8.

At 19, a suitable reinforcing band may be provided at one edge of wall 8. Band 19 as well as the nipples 16 are preferably electrically welded to the wall 8.

To facilitate cleaning of the space 15, a suitable number of removable plugs are provided at 20 to detachably enter sockets 21 which may be electrically welded to the wall. 8

A socket 22 may span the walls 9 and 10 and be constructed to mount a spark plug for the cylinder to which it is attached.

A modified form is shown in Figures 5 and 6 of the drawing. In this form, the air starter base is designated 23 and is disposed on the wall 10 rather than at the side of the wall 8 as in the other figures. The nozzle is designated 24 and spans the transverse walls of the inner and outer sections. The starter base in this form of course is adapted to be welded, preferably electrically, to the transverse walls of the inner and outer sections.

As merely practical embodiments of several forms have been illustrated and described, it isto be understood that changes within the details may be resorted to provided they fall within the spiritand scope of what is claimed.

Having thus described my invention, what I claim is:

A cylinder head comprising hollow cylindrical members of relatively difierent diameters and altitudes and closed at their upper ends, the members fitting one within the other With their end and lateral walls relatively spaced tubes positioned between the lateral Walls of said members and passing through the end wall of the larger member, and said tubes being Welded to said lateral walls from end to end of the lines of contact of the tubestherewith and to the end wall to hold the members against relative lateral and longitudinal movements.

In testimony whereof I affix my signature in presence of two witnesses.
